Your automatic transmission is a A240E. This transmission uses Dextron II as fluid. Research A240E and read up on it. My brother had a nice, fully optioned, black leather seats, automatic 86 MR2 and HATED it. It would take several miles of interstate driving to get it to go into OD (overdrive) even when the thermostat is working correctly. Eventually he bought a manual shift 86 MR2. Welcome to the family and enjoy your MR2. Much to be learned about it and this forum is a wonderful resource.
